.... These methods can be classified by the method of excitation and the nature of x-ray detection. The excitation source creates inner electron shell atomic vacancies that cause x-ray emission when filled by outer electrons. X-ray fluorescence (XRF) uses x-rays for this purpose; electrons are used to cause...
